摘要： A surgical instrument includes an end effector and a handle assembly. The end effector is configured to operate at a first energy level and at a second energy level. The end effector is further configured to transition between an open position and a closed position. The end effector is configured to grasp tissue in the closed position. The handle assembly includes a body, a trigger, and an activation element. The trigger is configured to pivot in a first direction relative to the body to actuate the end effector from the open position to the closed position. The activation element is configured to activate the end effector at either the first energy level or the second energy level. The trigger is configured to either activate the activation element or determine whether the end effector operates at the first energy level or the second energy level.

摘要： Surgical devices and methods are described herein that provide improved motor control and feedback, thereby combining advantages of manually-operated and powered surgical devices. In one embodiment, a surgical device includes a proximal handle portion that includes a motor, a distal end effector coupled to the handle portion, and a cutting element configured to cut tissue engaged by the end effector, wherein the motor is configured to supply power that moves the cutting element. The device also includes a motor control mechanism configured to cause the amount of the power to dynamically change in response to a manual user input when the cutting element is moving.

摘要： Methods and devices for allowing articulation of an end effector on a surgical instrument are provided. In one embodiment, a surgical device can include a flexible neck portion having an end effector coupled to a distal end thereof. The flexible neck portion is configured to bend to as to allow the end effector to articulate. The flexible neck portion can include a monolithic flexible outer shell defining an inner lumen extending therethrough. At least one flexible divider can be disposed within the inner lumen such that it separates the outer shell into elongate pathways configured to receive articulation members extending through the shaft assembly and the flexible neck and coupled to the end effector to cause articulating movement thereof.

摘要： An end-effector is disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw and an electrode configured to electrically couple to an opposite pole of the electrical generator. In one configuration, the electrode is segmented. In another configuration, the ultrasonic blade includes electrically insulative material deposited on selected areas to prevent electrical shorting in the event of the ultrasonic blade contacts the electrode. In another configuration, the clamp arm, the ultrasonic blade, or both include selectively coated components.

摘要： An end effector is disclosed comprising an ultrasonic blade and a clamp arm pivotable relative to the ultrasonic blade to capture tissue therebetween. The clamp arm defines an arcuate surface configured to at least partially surround the ultrasonic blade. The clamp arm comprises a circuit positioned on the arcuate surface. The circuit comprises an electrode layer configured to transmit RF energy to the tissue positioned between the clamp arm and the ultrasonic blade, a compressible layer positioned between the electrode layer and the arcuate surface, first pressure sensor layer positioned beneath the compressible layer between the compressible layer and the arcuate surface, and a second pressure sensor layer positioned above the compressible layer. The compressible layer is compressible to allow the electrode layer to deflect away from the ultrasonic blade. The compressible layer is compressible to allow the second pressure sensor layer to deflect away from the ultrasonic blade.

摘要： Devices and methods for articulating a distal end of a surgical device are provided. In one exemplary embodiment, the device includes an articulation joint that includes both an inner guide and an outer sleeve. The inner guide includes one channel extending therethrough that receives both a cutting mechanism and a closure band. Further, an outer surface of the inner guide, in conjunction with the outer sleeve, can define two additional channels that each receive an articulation band for articulating an end effector coupled to the articulation joint. The outer surface of the inner guide can include a plurality of ribs that also help define the two additional channels. Further, the outer sleeve can include a plurality of slots formed in it to improve flexibility and stability. Additional configurations of articulation joints, and configurations of components of a surgical device, are also provided, as are methods for using the same.

摘要： A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state.

摘要： The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

摘要： An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.
